Expensive and well-machined match-grade pistols demonstrate a higher accuracy than normal handguns, capable of groupings of 1.25 inches at 25 yards, which is about 5 MOA (equivalent to about 30 mm at 25 meters, which is 1.2 mil). [10]
The subtension is linear with the distance, for example, at 500 yards, 1 MOA subtends 5.235 inches, and at 1000 yards 1 MOA subtends 10.47 inches. Since many modern telescopic sights are adjustable in half ( 1 / 2 ), quarter ( 1 / 4 ) or eighth ( 1 / 8 ) MOA increments, also known as clicks , zeroing and adjustments are ...
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...

Since 1990, when long-term sand volume measurements began, Palm Beach's 12.2 mile-shoreline has experienced a net gain of 4.8 million cubic yards of sand, said Mike Jenkins, a coastal engineer ...
<1 mph Smoke rises vertically. Light Air 0.3-1.5 m/s 1–3 mph Direction shown by smoke drift but not by wind vanes. Light Breeze 1.6–3.3 m/s 4–7 mph Wind felt on face; leaves rustle; wind vane moved by wind. Gentle breeze 3.4–5.5 m/s 8–12 mph Leaves and small twigs in constant motion; light flags extended. Moderate breeze 5.5–7.9 m/s
The value of 1 MOA @ 100 yds is 1.04719758 inches. In linear progression, 1 MOA is equal to 0.52359879 inches @ 50 yds and to 2.09439516 inches @ 200 yds. It is basically the measure of the opposite side of a rectangle triangle with a 1 MOA (1/60th of 1 deg) "A" angle".
